How It Works
Choose any API — Claude, GPT, Gemini, Mistral. Pick your token volume, pay today's rate, and lock it permanently. Even if prices rise 10x, your rate never changes.
Need Claude just once? Pay a micro-amount in ETH via Robinhood and get instant one-time access. No account, no subscription, no commitment. Use the API and move on.
Step by step

Pay with ETH via Robinhood for pay-as-you-go, or lock in with any payment method for reservations.

When you reserve API calls, you pay the current market rate. This rate is permanently locked for your reserved volume. Even if the provider raises prices by 5x or 10x, your reserved calls remain at the original price you paid.
Simply select an API, pay a micro-amount in ETH through Robinhood, and get instant one-time access. No account needed, no subscription. You pay for exactly one call and you're done.
ETH enables frictionless micro-payments — fractions of a cent per API call. Robinhood makes it accessible to everyone without needing a crypto wallet or exchange account. Just use the ETH in your Robinhood balance.
Not yet. Transferability and a secondary marketplace are on the roadmap for a future update.
We support 30+ API providers including Claude (Anthropic), GPT-4/5 (OpenAI), Gemini (Google), Mistral, Llama, Cohere, Stability AI, and more. All are available for both reservation and pay-as-you-go.
For reservations, we offer a full refund for unused calls or equivalent credit toward another provider. Pay-as-you-go calls are executed instantly so there's no risk.
No minimum. You can make a single API call for fractions of a cent in ETH. For reservations, the minimum is 10,000 calls.
Instant. Once your ETH payment is confirmed (typically under 2 seconds via Robinhood), the API call executes immediately and you receive the response.
Lock prices for the long haul, or pay a fraction in ETH for a single call. Either way, you're in control.
